摘要： The invention relates to a wind power plant, comprising a generator driven by a rotor in order to generate electrical power and a control means that comprises a pitch module for adjusting a pitch angle of blades of the rotor (2), and wherein the control means has an input for a required power reserve and determines a target pitch angle depending on an operating point of the wind power plant. The invention further relates to a secondary pitch controller, which comprises a detector (43) for available power and a dynamic offset module (44), wherein input signals for the available reserve power determined by the detector, the required reserve power and the generated electrical power are applied to the dynamic offset module, which is designed to determine a value for a pitch angle offset. An activation element (40) is further provided, which varies the target pitch angle by the pitch angle offset. Thanks to said link, in particular the variability of the pitch angle offset, the offset required for the desired controlling power can be determined taking into account the current working point of the wind power plant.

摘要： The present invention relates to control of the power output of wind turbine generator that operates in derated mode to generate a produced power output level lower than an available power level. A pitch system 48 sets the blade pitch of a rotor to a pitch value based on the received power reference signal 40. A power system 43 controls the produced power output power level of the wind turbine to the requested power output level. Moreover, the blade pitch of the rotor is further controlled by a pitch feedback control loop 47 that modifies the pitch value based on a difference between the produced power output level 46 and the requested power output level 40.
